    // is_Write_Same_Supported
    //
    //! \brief   This function checks if the device supports write same. On SCSI, it returns the max number of logical blocks per command, which is reported in an inquiry page. On ATA, this will return MaxLBA - startLBA and whether SCT write same is supported or not

    //  Entry:
    //!   \param[in] device = file descriptor
    //!   \param[in] startingLBA = The LBA that you want to start write same at
    //!   \param[in] requesedNumberOfLogicalBlocks = the number of logical blocks you want to erase starting at startLBA (also known as the range)
    //!   \param[out] maxNumberOfLogicalBlocksPerCommand = this is the range the device supports in a single write same command (0 means that there is no limit)

    //! \brief   This function will get the write same progress for you. This only works on ATA drives (and it is calculated progress, not drive reported) since SCSI does not report and progress on write same

    //!   \param[in] startingLBA = This is the LBA that the write same was started at (used to calculate progress)
    //!   \param[in] range = this is the range that the write same is being run on (used to calculate progress)
